Description

Self-propelled grain harvesting machine

The utility model relates to a kind of self propelled harvester tool of farming cereal, and it is particularly suited for the harvest operation of rice grain.

Introduce according to " practical baby combine technology " book 64-67 face that the chief editor of Tianjin Bureau of Agricultural Machinery Administration, Chinese agriculture publishing house publish and distribute: " supporting baby combine adapts to the national conditions that the present rural economy level of China is lower, scale of agricultural operation is small and scattered with small tractor; It is the product of China market economic development; Over a period to come, will be one of leading products of China's crops results, have bright development prospect.At present, there is family surplus the unit 200 that is engaged in baby combine scientific research, production in China.The ripe type that some and 8.8-18.3 kilowatt of (12-25 horsepower) tractor have been arranged.Simultaneously, small self-propelled combine-harvester has also had certain development." this book also point out the problem that current development baby combine exists " ... the degree of product standardization is low, type is mixed and disorderly, the existing formula, double dynamical of putting on a suit of armour, once cutting, secondary cut, multiple patterns such as axial flow is cleaned, air flow cleaning make troubles for popularization and after-sale service; The 3rd, reliability of products is still very low ... in the existing product, be used for the more of getting wheat, and the less of paddy rice gathered in utilization, main cause is that walking problem in paddy field does not solve.In view of the road of external advanced country combine development, automation, the computerization that be convenient to improve grain header also need to develop self-propelled baby combine." fact is really as described in submitting a written statement to a higher authority; as the patent No. is that " the small-sized assembly type combine " of 93204980.x needs and 15 horsepowers handcar assembly; the star-wheel that is provided with secondary cut band conveying mechanism is held up the standing grain standing header; can unite and finish cutting; threshing, carry, clean, pack operation, but but getting wheat and powerless only to the harvesting of paddy rice.For another example number of patent application be 91104455.8 " small rice-wheat harvester of continuously self-walking type " it be with manpower or simple and mechanical be power source, drive knife section by the transmission by gear, chain etc. of manpower turning handle or simple dynamic power machine and reach the harvesting purpose with fixed blade cutting.It only can finish the cutting action in the wheat rice results, and unresolved conveying, threshing, a complete set of harvest operation of cereal such as cleans.And for example the patent No. is 93215677.0 " novel self-propelled grain combine ", carry out the harvest operation of wheat, rice, soybean though can walk automatically, have flexible operation, fuel-economizing, advantage that percent of loss is low, but need two cover power respectively by counter pulley deceleration harvesting mechanism and running gear, its structure still is complicated, and job area mainly is cereal such as nonirrigated farmland results wheat, beans, especially then is difficult to harvest operation in the soft rice field of mud pin for paddy rice.

Purpose of design of the present utility model is that design provides a kind of single action power of using will gather in the crops and supporting, simple in structure, the quick detachable installation of running gear, dependable performance, higher, the automatic walking of efficient, the Work machine that can carry out rice harves.
